The structure of 113 interferes. When the second door body 220 is turned over to the closed state, the guide flanging part protrudes into the avoidance groove 101, and the outer surface of the second door body 220 is in contact with the groove wall of the avoidance groove 101. stick. The joint between the second door body 220 and the left frame 112 is the gap between the outer surface of the second door body 220 and the groove wall of the escape groove 101, and the escape groove 101 makes The seam cannot go straight through the confidential space and the width of the seam is not greater than 2mm, and the depth of the seam can be not greater than 25mm by rationally designing the size of the avoidance groove 101 .

Referring to Fig. 4, the right side of the first door 210 is provided with a flange 211, and when the cabinet door is in the closed state, as shown in Fig. 5, the left side of the second door 220 overlaps On the flange 211, the seam between the second door body 220 and the first door body 210 cannot be directly connected to the confidential space, and the width of the seam is not greater than 2 mm, and the door can be designed reasonably. The size of the body, so that the depth of the seam is not greater than 25mm. Those skilled in the art should understand that the flange 211 can be arranged on the left side of the second door body 220, and the right side of the first door body 210 overlaps the flange 211 when the door is closed. ; or the right side of the first door body 210 and the left side of the second door body 220 are respectively provided with flange structures that can overlap and cooperate with each other when closing the door.

Since the improvement of the present application does not involve the electronic lock 230, it is not repeated here.

When the first door body 210 and the second door body 220 are turned over to the closed state, the front surfaces of the first door body 210 and the second door body 220 do not protrude from the front of the door frame 110 The surface effectively reduces the folded volume and improves the aesthetics.

Referring to Figures 14-17, the side plate 120 is provided with two pieces, the front side of one side plate 120 is hinged with the left frame 112 through a connecting assembly, and the front side of the other side plate 120 is hinged with the left frame 112. The right frame 114 is hinged by connecting components. Specifically, the side panel 120 is disposed at the rear of the door frame 110 , and the side panel 120 can be folded toward the inside of the door frame 110 and folded on the rear side of the door frame 110 .

Hereinafter, the right frame 114 and the right side panel 120 are taken as examples for description.

The connection assembly includes a first rotating part 121 , a second rotating part 1141 , a first limiting part, a second limiting part and an external connection part.

The first rotating part 121 is arranged on the inner side of the mating surface of the front side of the side plate 120 (the inner side refers to the side close to the inside of the cabinet body 10), and the second rotating part 1141 is arranged on the right side. Inside the mating surface of the frame 114 , the second rotating portion 1141 cooperates with the first rotating portion 121 to form a hinge, so that the side plate 120 and the right frame 114 form a rotational connection. In this embodiment, the upper part, the middle part and the lower part of the side plate 120 are respectively provided with a first rotating part 121, and the second rotating part 1141 is provided in a one-to-one correspondence with the first rotating part 121, but this Those skilled in the art should understand that the rotating part in the middle is not an essential setting. In this embodiment, the first rotating part 121 and the second rotating part 1141 are a pair of hinge structures, but those skilled in the art should understand that the first rotating part 121 and the second rotating part 1141 Other structures that can realize the rotational connection relationship can be used.

The first limiting portion is arranged on the mating surface of the front side of the side plate 120 and extends vertically along the side plate 120 , and the length of the first limiting portion is the same as that of the side plate 120 The length of the mating surface is the same. The second limiting part is arranged on the matching surface of the right frame 114 and extends vertically along the right frame 114, and the length of the second limiting part is the same as the length of the matching surface of the right frame 114 unanimous.

Referring to FIG. 17 , the first limiting portion is a limiting slot, and the limiting slot includes a first slot segment 122 and a second slot segment 123 that are connected. The first groove section 122 is perpendicular to the front side surface of the side plate 120, and the second groove section 123 forms a first angle with the first groove section 122 (in this embodiment, the first angle is about is 135°), and the second slot section 123 faces the outside of the cabinet body 10, so that the first slot section 122 and the second slot section 123 form a preset channel with bends, and the first The slot section 122 forms a rear section of the preset channel, and the second slot section 123 forms a front section of the preset channel. In this implementation, the limiting groove is jointly formed by the first sheet metal part welded to the side plate 120 (the first sheet metal part is filled with black dots in FIG. 17 ) and the bending structure of the side plate 120 .

Referring to FIG. 17 , the second limiting part is a limiting hook, and the limiting hook includes a first hook segment 1142 , a second hook segment 1143 and a connecting segment 1144 connected. In this implementation, the limit hook is formed by a second sheet metal part (the second sheet metal part is represented by honeycomb filling in FIG. 17), and the connecting section 1144 is L-shaped, connected to the first hook section 1142, The connecting section 1144 is used for welding with the right frame 114 . The mating surface of the first hook section 1142 and the right frame 114 forms a second included angle (the second included angle is about 110° in this embodiment) and is inclined toward the inside of the cabinet body 10. The second hook The segment 1143 is parallel to the mating surface of the right frame 114 and extends toward the inside of the cabinet body 10 . However, those skilled in the art should understand that the limiting hook can be directly formed by the bending structure of the right frame 114, and in this form, the connecting section 1144 is not necessary, and mainly cooperates with the limiting groove are the first hook segment 1142 and the second hook segment 1143 .

In some other embodiments, the limiting groove of the present application can also have another design: the sheet metal part is directly bent once to form a limiting groove inclined at an acute angle, and the shape of the limiting groove is equivalent to deleting this embodiment. The first groove section 122 is directly bent to form the second groove section 123. When used in cooperation, the front end of the limiting hook is directly inserted into the acute corner, so as to realize the function of the limiting groove of this application. However, it is more difficult for sheet metal processing to directly fold out acute corners, and the matching error tolerance rate of this shape is low. The limit hook must be accurately inserted into the acute corner, otherwise there will be a fit error, which may lead to the failure of the limit function. Therefore, the limit groove has relatively high requirements on machining accuracy. In contrast to the structure of the limiting groove of the present application, first bend once to form the first groove section 122 at a right angle, and then bend the first groove section 122 a second time to form an obtuse angle The second groove segment 123 . The limiting groove of the present application is difficult to process, and because the first groove section 122 has a certain depth, a large space is formed in the groove to facilitate the subsequent cooperation of the limiting hook, so the matching error tolerance of the limiting groove of the present application is relatively high , It is not easy to have matching errors, and the requirements for machining accuracy are low.

Referring to FIG. 17 , the outer connection portion is arranged at a position where the fitting surface of the right frame 114 is close to the outside of the cabinet body 10 , and the length of the outer connection portion is not less than the length of the fitting surface of the right frame 114 . The external part includes a shielding section 1145 and a supporting section 1146 connected thereto. The shielding section 1145 is perpendicular to the rear surface of the right frame 114, when the side panel 120 is unfolded to the point where the first limiting part is matched with the second limiting part (that is, the side panel 120 is in an unfolded state) , the shielding section 1145 abuts against the outer surface of the side plate 120 , blocks the joint between the matching surface of the side plate 120 and the matching surface of the right frame 114 , and is connected to the side plate 120 The outer surface forms a new appearance face seam. The supporting section 1146 is connected to the shielding section 1145 at an included angle, so that the shielding section 1145, the supporting section 1146 and the rear surface of the right frame 114 form a right-angled triangle structure in section, increasing the structural strength, and Improve the aesthetics of the cabinet.

In Fig. 12, the rear surface of the left frame 112 is also provided with the second limiting portion and the outer connection portion. In order to clearly show the structure, the second limiting portion located on the rear surface of the left frame 112 And the outer connection portion is marked with the same set of symbols as the second limiting portion and the outer connection portion disposed on the right frame 114 .

During the flipping and unfolding process of the side plate 120, the limiting hook is inserted into the limiting groove, and when the side plate 120 is turned over to the unfolded state (as shown in FIG. 17 ), the side plate 120 Parallel to the right frame 114 , the front end of the second hook section 1143 abuts against the inner wall of the first groove section 122 , and the shielding section 1145 abuts against the outer surface of the side plate 120 . In some other embodiments, the inner wall of the first slot section 122 may be provided with a card hole, the front end of the second hook section 1143 may be provided with a tab, and the front end of the second hook section 1143 is in contact with the first slot. When the inner walls of the segments 122 abut against each other, the tabs are snapped into the snap holes to form a further limit.

The connection assembly proposed in this embodiment at least includes the following beneficial effects:

First, the joint formed between the mating surface of the side plate 120 and the mating surface of the right frame 114 cannot pass through the confidential space through the cooperation of the bending structure of the limiting hook and the limiting groove And the width is uniform. Further, the seam of the new appearance surface formed by the outer connection part makes the seam between the side panel 120 and the right frame 114 bend more, and strengthens to ensure that the seam cannot directly lead to the confidential space, and has It is beneficial to improve the aesthetics of the appearance surface.

Second, the force generated by the mutual abutment of the limiting hook and the limiting groove can reduce the joint width between the matching surface of the side plate 120 and the matching surface of the right frame 114 to Not greater than 2mm, it is beneficial to prevent the side plate 120 from being partially deformed when subjected to external force, so as to ensure that the width of the seam remains uniform all the time without local expansion. Furthermore, the force generated by the abutment makes the outer surface of the side panel 120 closely abut against the shielding section 1145 , and the formed seam with a new appearance can more easily reach a width not greater than 2mm.

Thirdly, the cooperation between the limiting groove and the limiting hook can limit the side plate 120 to only rotate back to the folded state along the folding path to get away from the door frame 110 . Specifically, it is assumed that the forward rotation along the folding path is turned over to the unfolded state, and the reverse rotation along the folding path is turned over to the folded state. When the side panel 120 is turned over to the unfolded state, the second limiting portion and The first limiting parts cooperate with each other, and only allow the side panel 120 to turn back to the folded state in the reverse direction along the folding path, and not allow the side panel 120 to move along other paths. Due to the above limitation of the limiting part, when the rotational connection between the second rotating part 1141 and the first rotating part 121 fails, the only way to make the side plate 120 detach from the door frame 110 is that the side plate 120 Reverse rotation along the folding path changes back to the folded state. In fact, when the folding cabinet is in the normal unfolded state, the reverse degree of freedom of the folding path is generally limited (restricted by the bottom plate 140), so even in the extreme case of failure of the rotating connection structure, the mutually cooperating limiting parts are still It can ensure that the connection between the side panel 120 and the door frame 110 will not be directly separated, and further ensure the safety performance of the folding cabinet.

Referring to Figures 18-22, the assembly surface of the rear side of the side panel 120 is detachably connected to the side of the back panel 130 through an assembly assembly, and Figure 18 shows the connection between the back panel 130 and the side panel 120.

The third included angle is between 95°-125°, and in this embodiment, the third included angle is 120°.

Referring to FIGS. 21-22 , the second bending portion includes a second connecting side 131 , a second straight side 132 , a second folded side 133 and a second guiding side 134 which are sequentially connected. The second connecting edge 131 is vertically connected to the back panel 130 to form a bend and extends forward, and the second straight edge 132 is vertically connected to the second connecting edge 131 to form a bend and extends toward the side panel 120, the second edge 133 is vertically connected to the second straight edge 132 to form a bend and extends backward, and the second guide edge 134 is connected to the second edge 133 at a fourth angle A bend is formed and extends toward the second connecting side 131 . The fourth included angle is between 90°-110°, and in this embodiment, the fourth included angle is 100°.

In this implementation, the third included angle between the first guide edge 127 and the first folded edge 126 is an obtuse angle so that the opening of the first bending portion (the first guide edge 127 and the first folded edge 126 The distance between the inner surfaces of the side plates 120) is wide at first and then narrow, and has the function of installation guide, which is convenient for users to align and insert the second bending part for installation. After the second bending part is installed in place, the second bending part Two ends of the guide edge 134 abut against inner surfaces of the first guide edge 127 and the side plate 120′ respectively, so that the connection and cooperation are reliable. In addition, the processing of the bent portion is facilitated.

Referring to FIG. 22 , when the side panel 120 and the back panel 130 are in the unfolded state, the first bent portion and the second bent portion cooperate with each other, and the end of the second guide edge 134 is in contact with the The ends of the first guide edge 127 are abutted against each other so that the joint between the first straight edge 125 and the second connecting edge 131 is narrowed, specifically, the joint is not greater than 2 mm. The seam has a bend, and when the length of the second connecting edge 131 is set to be less than 25 mm, the depth of the seam can be guaranteed to be no greater than 25 mm.

In addition, the first folded edge 126 is in contact with the second straight edge 132 , the second folded edge 133 is in contact with the inner surface of the side panel 120 , and the outer surface of the first connecting edge 124 is in contact with the inner surface of the side panel 120 .
